Price List for Low-Loss Optical Modules for Data Center Interconnection

Low-loss tunable optical modules for DCI range from $600 for 400G QSFP-DD modules to $1,900 for long-reach 800G OSFP modules, with third-party alternatives often offering 20–50% savings. Typical Price Ranges by Module Type and Speed100G QSFP28: Third-party short-reach modules can start as low as $35, while OEM LR4/CWDM4 modules typically range from $200–$500 depending on reach and vendor support. 200G QSFP56 / QSFP-DD: Market prices generally range from $600–$1,000 for standard DCI-compatible modules, with long-reach or tunable variants at the higher end.

400G QSFP-DD: Coherent DCI modules are priced around $600–$800 for metro distances, with OEM modules commanding a premium. 800G OSFP / QSFP-DD: High-end tunable modules for long-reach DCI applications cost $1,100–$1,900, depending on reach (DR8 vs FR4), vendor tier, and volume discounts.

Factors Affecting Pricing

Vendor Tier: OEM modules (Cisco, Arista, Juniper) typically cost 30–50% more than third-party compatible modules. Reach and Technology: Modules with longer reach (FR4, ZR/ZR+) or tunable wavelengths are more expensive due to complex optics and coherent DSP technology. Volume Discounts: Large-scale deployments (1000+ units) can reduce per-unit cost by 10–30%.

Power and Cooling: Modules consume 3. 5–20W depending on speed and reach, impacting operational costs. Support and Warranty: OEM modules often include extended support and calibration, which can justify higher prices.

Practical ConsiderationsThird-party modules can provide significant cost savings without sacrificing interoperability, especially for CWDM4, LR4, and FR1 modules. Tunable coherent modules (e.g., Marvell COLORZ 400/800, GIGALIGHT DCO) are optimized for DCI, offering low latency, high density, and long-reach connectivity up to 2,000 km. Deployment Costs: Total cost includes not only the module but also cabling, patch panels, and monitoring software.

For example, a 200-port QSFP28 deployment may incur $15,000–$30,000 in cabling infrastructure.
